How can I verify jwt using "djangorestframework-simplejwt"

Question

I am beginner in drf (Django rest framework), and now I'm making authorization logic with JWT. I heard that djangorestframework-simplejwt is most famous library in drf.

I saw docs, but there are no way to verify token. (exactly i cannot find it :( )

thank you.

you only need to verify it by the login API, and you have already TokenObtainPairSerializer and TokenObtainPairView — K.D

Thank you for your opinion @K.D Yeah, and I know that there is also TokenVerifyView that verify token, but i want verify token in middleware with verifing function like make token with function (which says in docs.) — seongkyulim

in JWT you can verify if a token is valid by decoding it, your key = any key used during token creation, your algorithm = algorithm used during token creation, token = value of the token to decode

import jwt
decoded_result = jwt.decode(<token>, key=<your key>, algorithms=<your algorithm>)
print(decoded_result)

this prints decoded payload from your token if valid, else raises jwt exceptions which can be caught in a try-catch block for further processing.

Your opinion is that It is no problem to use any library for decoding jwt if algoriths are matched. Is it right ??

oh sorry for missing out on mentioning the library, i've used PyJWT for the above piece of code, you can find info regarding the library here.
